The only thing that will turn this world around is if human beings change themselves, or else we are in great danger of destroying ourselves. We are utterly controlled by our minds, and we still live defensively like we are in the jungle even though many of us (especially those in power) do not have to struggle to survive. But we still act like animals, and if anyone poses a threat to our ego, we want to act defensively and often violently. We are still animals even in our civilized conditions.
Jesus said that he would come back to earth, but he did not mean physically. If we overcome our minds and become spiritual, that is the real meaning of heaven on earth. The apocalypse just means the "lifting of the veil", it does not mean the end of the world. But it could be the end of the world as we [i]know[i] it if we lift the veil of our egos and surrender to the goodness underneath.
